A further object of the invention is to provide a device of the character described, which is adapted for readyinstallation in a window frame of varying widths to form a strong and compact guard or barrier therefor, for preventing passage therethrough, and means associated with said device, for lockingthe same in operative position said means being operable only by those authorized to o i said barrier or guard and removing the same samba-e. window me- Astill further ob'ect of the invention is to provide a guardo. the character described comprisingja plurality of interengaging rods "him" "when infully assembled position in a Q w a window form a strongand compact guard therefor, said guard being collapsible when not in use whereb y the same be foldedlinto'a'neat and compact package which may be "easilytransported from la t classerate the same for unlocking the Serial No. 323,233.

A still further object ofthe invention is to provide a novel and improved adjustable and collapsible window guard of the character described, which will be simple in construction, easily assembled and locked in place in a window frame, of varying Widths, readily removable and collapsed into a small and compact package for transporting the same from place to place, cheaply manufactured, and efficient in carrying out the purposes for which it is designed.

lVit-h the foregoing and other objects in view, which will appear as the description proceeds, the invention consists in certain novel and improved features of construction, arrangement, and combination of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, sizeand minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

Stated generally, the invention comprises a pair of upright rods adapted to be positioned below the upper sash of a window frame and fitted in the grooves in which the said upper sash slides. The said upright rods are provided in their inner sides with a plurality of equally spaced openings in which are adapted to be received the ends of suitable laterally disposed rods, the free ends of said lateral rods extending to a point near the middle of the window, and mounted upon corresponding free ends of said lateral bars are adjustable sleeves provided with suitable set screws adapted forsecurely locking said sleeves on said lateral. rods. The set screws are only engageable by a suitable key for tightening and loosening the same, thereby preventing the unauthorized unlocking of said sleeves and thereby the removal of said grating. The whole of the above grating may be readily disassembled when not in use and collapsed to form a neat and compact package, which may be easily carried from place to place.

For the purpose of facilitating an understanding of my invention I have illustrated in the accompanying drawings a preferred emoperate in the usual manner.

bodiment thereof, from an inspection of which, when considered in connection with the following description, my invention, its mode of construction, its advantages should and appreciated.

Referring to the drawings, in which similar characters of reference are employed to indicate corresponding or similar parts throughout the several figures in the drawings:

Fig. 1, is a side elevational view of the guard in fully assembled and locked position mounted within the fraine of a windowg .Fig. 2, isa cross sectional view takenon line 2-2 of Fig. 1 I

Fig. 8. is a fragmentary view in perspective of the side rods; i

Fig. i, is an enlarged elevational view of one of the sleeves connecting the free ends of a pair of lateral rods; and

is a view in perspective of the inner ends of thelateral rods.

Referring to thedrawings more specifically, the referencecharacter 1,.designates a win dowframe having a lower sash 2, and an upper sash 3. The sides of thewindow frame, 1,.are provided usual sash grooves be readily understood 4 with the at, in which the sash 3, is slidably mounted. The grating'is. adapted to be mounted in the window frame directly beneath the upper sash 3, so as to extend on each side thereof into the grooves l. f '8 The grating is composed of upright or vertically disposed rods or bars 5-, of which there are two, one for each side of the window frame, said rods being of identical construction and and obviously interchangeable. The rods 5, are adapted to be disposed and fitted within the grooves l, where it will prevent the lowering of the up er sash 3, but will not interfere in any way with the lowering and raising of the lower sash 2. which may Each of the rods 5, are provided on their inner face with suitable openings or bores 6, equally spaced from each other, and provided with a flattened surface or side 7, for a purpose to be presently described. Lateral or cross rods, 8, are provided, saic rods having one of their ends reduced in diameter as shown at 9, which reduced end is adapted to be received in an opening 7, in the side rod 5, one face or side f reduced end being flattened to corre nd to the st 1' in the opening 6, whei eby when said rod 8, is in assembled position, the same will not be rotatable in the opening 6, wh eby whcnsaid rods 8, are in assembled.position, the same will not be rotatable in the openings 6.. The rods 8, are of identical construction, shape and size and may, of course, be readily interchanged.

Mounted on the free inner ends of any pair of corresponding lateral or cross rods 8, is a sleeve member 10, said sleeve being adapted assembly, and many of v sleeve 10, and engage ece ve the ends of a corresponding pair ateral rods, and is slidably adjustable -0n. The sleeves 10, are laterally adjuste with respect to the lateral rods 8, by the lescoping of the free ends of said rods 8, it iin the sleeve 10, by means of which the rating is adjustableto fit window casings of arying widths.

For securing the grating in its lateral adj ustable position, there are provided on each of the sleeves 10, adjacent each end thereof a uitable set or look screw 11, each of which set screws is provided with a recess or depression 19., in its outer end or head, which recess may be of various shapes, whereby. a s ecial key will be required for loosening or tightening the said set screws, consequently, the set screws ll,cannot be loosened by an unauthorized person. The set screws 11, are adapted to extend through the wall of the the rod 8, for securely locking the sleeve on the rod 8, in the desired adjusted position.

In operation, the grating may be assembled in the window frame as follows: The vertical rods or bars 5, are disposed within the grooves l, of the window casing, with theopenings 6, therein, facing inwardly and towards each other. The crossrods 8, are then fitted into the said openings 6, and the sleeves 10, are then slipped over the inner ends of each pair of corresponding cross rods, and the set screws 11, tightened for securely locking the grating in place, said sleeves being disposed or positioned, so that the set screws therein will face towards the inside of the room, in which the window frame is located, thereby preventing anyone from the outside of the building to operate said screws. The grating is now in its fully assembled and adjusted position in the window casing and is securely locked therein, and when in this position it will be noted that the lower window sash may be lowered and raiser at will. ,To remove the grating, the set screws are loosened, by means of the special lrey provided therefor, the sleeves are then moved out of engagement with the inner ends of the rods upon which it is mounted, and the rods 8, then disengaged from the side members 5, and removed, after which the side rods 5, may be removed from the grooves The said rods 5, 8, and the sleeves 10, may easily be rolled into and formed into aneat and compact package which may be easily transported from place to place, or packed away into a minimum of space.

From the above it will be noted, that a noveland improvedwindow guard which is adjustable and collapsibleis provided, which will positively prevent entrance of an unauthorized person through awindow' into a building, and that the device-maybe readily and easily installed or removed byone autho ized to do so.

lt will also be noted, that the grating consists of a minimum of parts which may be readily interchanged, thus producing a device which may be cheaply and economically manut'actured.

It is believed that my invention, its mode of construction, and many of its advantages should be readily understood from the foregoing without further description; and should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention, as defined in the appended claims.
